ZT Gearbox Fill Plug

ZT Gearbox Fill Plug

This fill plug is a direct replacement component for the proprietary ZT gearboxes used exclusively on Continental (CBMW) concrete mixers. It securely seals the gearbox oil fill port to maintain proper fluid levels and prevent the ingress of dirt, water, and concrete debris into the gear system. Operators typically replace this plug during routine gearbox maintenance, fluid changes, or if the original plug becomes stripped, lost, or damaged. Maintaining a secure seal is critical to preserving the lifespan of the ZT gearbox's internal bearings and gears.
